Large-N $\beta$-function for superconducting films in a magnetic field

Abstract

By considering the large-N Ginzburg-Landau model, compactified in one of the spatial dimensions, we determine the beta-function and find an infrared stable fixed point for a superconducting film for dimensions 4<D<64<D<6. We find that this fixed point is independent of the film thickness (LL). For the physical dimension D=3 we conclude that if a transition exists it is not a second order one.
